Frequently Asked Questions - TX20U MITSUBISHI

How do I replace the lamp on the Mitsubishi TX20U?
Turn off the projector and unplug the power cord. Wait at least 45 minutes for the lamp to cool. Loosen the screw on the lamp cover, slide the lock bar, and remove the cover. Pull out the old lamp by its handle. Insert the new lamp (model VLT-TX20LP) securely, replace the cover, and tighten the screw. Power on and reset the lamp timer via the INSTALLATION > ADVANCED MENU > LAMP TIME RESET. Do not look directly into the lens when the lamp is on.
How can I correct a trapezoid (keystone) distortion?
Press the KEYSTONE button on the remote or projector. Use the ▲/▼ buttons to adjust vertical distortion. For automatic correction, set AUTO KEYSTONE to ON in the INSTALLATION menu. Note that automatic adjustment may not work perfectly in moving environments like vehicles; in that case, set AUTO KEYSTONE to OFF and adjust manually.
What do I need to watch 3D content?
You need 3D content (from a compatible computer, DVD/Blu-ray player), and DLP™ Link™ active shutter glasses (not included). In the IMAGE menu, set 3D to ON and select the correct 3D FORMAT (AUTO for HDMI with identification, or SIDE BY SIDE, TOP AND BOTTOM, FRAME SEQUENTIAL depending on the source). Wear the glasses and turn them on. Avoid direct fluorescent light near the sensor.
What is the remote control operation range?
The maximum distance is about 10 m (32 ft) when pointed directly at the projector's sensor. When using the screen as a reflector, the distance should be 5 m or less. The sensor has a horizontal reception angle of about ±20° and vertical of about ±15°. Avoid direct sunlight or fluorescent light near the sensor.
How do I clean the projector and lens?
Turn off the projector, unplug the power, and let it cool. Use a soft dry cloth to clean the exterior and ventilation grilles. For stubborn dirt, dampen the cloth with diluted mild detergent. For the lens, use a standard lens-cleaning brush or lens tissue dampened with lens cleaning fluid. Never use benzene, thinner, or flammable solvents. Do not touch the lens with fingers.
How do I turn off the projector properly?
Press the POWER button on the projector or the STANDBY button on the remote. A confirmation message will appear; press the same button again within 10 seconds. The lamp turns off, and the STATUS indicator blinks green. Wait about 90 seconds until the indicator turns off, then unplug the power cord. Do not turn the projector back on immediately; wait about 10 minutes to avoid lamp damage.
How do I switch between input sources?
Press the SOURCE button on the remote or projector. A list appears on screen: COMPUTER1, COMPUTER2, HDMI1, HDMI2, VIDEO, S-VIDEO, LAN DISPLAY, USB DISPLAY, USB VIEWER. Use the ▲/▼ buttons to select and press ENTER. Alternatively, press SEARCH to automatically cycle through active inputs. Ensure the external device is turned on before switching.
Can I connect the projector to a network?
Yes. Connect an Ethernet cable to the LAN (RJ-45) terminal on the back. In the NETWORK menu, configure IP CONFIG (DHCP or manual IP address), PROJECTOR NAME, and NETWORK PASSWORD. For wireless, you need an optional USB wireless adapter (not included). The projector supports PJLink™, Crestron RoomView™, and AMX Device Discovery for remote management.
How do I use the digital zoom and adjust image size?
Press the DIGITAL ZOOM button on the remote. Use the +/- buttons to enlarge or reduce the image (maximum at factory default 0). Press ENTER to enter the SHIFT mode, then use the arrow keys to move the image in any direction. Note that zooming reduces resolution and may cause stripes. Avoid combining with keystone correction as the adjustable range narrows.
What should I do if the projector displays 'TEMPERATURE!!'?
This indicates the internal temperature is too high. Check that the ventilation grilles are not blocked and clean them if dusty. Ensure the ambient temperature is within the specified range (+5°C to +35°C). Move the projector away from heat sources or air conditioners. If the message persists, the lamp will automatically shut off. Turn off the projector, let it cool, and resolve any overheating causes before restarting.

Client Access License (CAL)

An application allowing multiple users to share a single operation system requires the standard Microsoft Windows server licenses. In addition to Windows Server Client Access License, Remote Desktop Services Client Access License (RDS CAL) is necessary for each end user or each device to access Windows server. When using Windows Multipoint Server, Windows MultiPoint Server 2011 CAL is also necessary. For details of Microsoft multiple user licenses, see the Microsoft website.

1. When the host computer OS is Windows XP, Windows Vista or Windows 7

For Windows XP, Windows Vista and Windows 7, only a single projector can run the thin client function. While using the desktop of host computer, you cannot use the thin client function on the projector.

MITSUBISHI TX20U - When the host computer OS is Windows XP, Windows Vista or Windows 7 - 1

2. When the host computer OS is Windows Server 2008 R2

Windows Server requests Client Access License (CAL). To access the host computer from a thin client computer or projector, two types of CAL are necessary: "Windows Server CAL" and "Windows Remote Desktop Service (RDS) CAL". "Windows Server CAL" offers two types of license system.

User CAL

With User CAL, you purchase CALs according to the number of users regardless of the number of thin client computers or projectors. User CAL is, therefore, recommended in the case that the number of system administrators or operators who operate thin client computers or projectors at multiple sites is smaller than that of the thin client computers or projectors.

MITSUBISHI TX20U - User CAL - 1

In the example above, the following licenses are necessary.

- Windows Server CAL (User CAL) x 2

- Windows RDS CAL x 2

Device CAL

With Device CAL, you purchase CALs according to the number of devices accessing to the host, regardless of the number of users who access the host via thin client computer or projector. Therefore Device CAL is recommended for the case that multiple operators share a thin client computer or projector.

MITSUBISHI TX20U - Device CAL - 1

graph TD
    A["Server"] --> B["Monitor"]
    B --> C["Projection Device 1"]
    B --> D["Projection Device 2"]
    B --> E["Projection Device 3"]

In the example above, the following licenses are necessary.

- Windows Server CAL (Device CAL) x 4 - Windows R D S C A L x 4

3. When the host computer OS is Windows MultiPoint Server

The concept of Windows MultiPoint Server is basically the same as that of Windows Server 2008 R2. It requires Windows MultiPoint Server CAL instead of Windows RDS CAL. Therefore, Windows Server CAL and Windows MultiPoint Server CAL are necessary for each user or device. When you use the desktop of host computer as one of computer terminals, Windows MultiPoint Server will also request a Windows Server CAL and Windows MultiPoint Server CAL for the desktop of host computer.

(Example 1)

When two users operate four computers or projectors as well as the desktop of host computer

- Windows Server CAL (User CAL) x 2 - Windows MultiPoint Server CAL x 2

(Example 2)

When six users operate four computers or projectors as well as the desktop of host computer

- Windows Server CAL (Device CAL) x 4 - Windows MultiPoint Server CAL x 4

Images are not displayed correctly.

Problem Solution
Projected images are shaking. Projected images are displaced.Check that the cable connected to the external device isn’t intermittent.Connect the cable’s plug with the external device’s connector firmly.Project an image containing a lot of characters without black areas and press the AUTO POSITION button.Some computers output out-of-spec signals on rare occasion. In such a case, change the setting of the SIGNAL DETECT in the FEATURE menu and press the AUTO POSITION button. If the position (and size) of the projected images is still incorrect, make adjustment using the SIGNAL menu. (For details, see flowchart on page 38.)
Projected images are distorted.Adjust the projector and the screen so that they are perpendicular to each other. (See page 17.)Use the flat screen.
Projected images are dark.Adjust BRIGHTNESS and CONTRAST in the IMAGE menu. (See page 26.)3D images displayed on the projector appear darker. It is normal and does not mean the projector is malfunctioning.When viewing 2D images, set 3D FORMAT to AUTO for HDMI input only) or set 3D in the IMAGE menu to OFF. (When AUTO is selected, only 3D images become darker.)Replace the lamp. (See page 67.)
Projected images are blurred.Adjust the focus. (See page 19).Clean the lens.Press theorbutton on the remote control to eliminate flicker.Adjust TRACKING and FINE SYNC. in the SIGNAL menu. (See page 30.)Set OVER SCAN in the SIGNAL menu to 100%. (See page 30.)Set the keystone adjustment to 0 using the KEYSTONE button.

(See page 26.)Adjust the projector and the screen so that they are perpendicular to each other. (See page 17.)
Afterimages persist on the screen.This phenomenon is improved by keeping projecting an evenly bright image. (Such “image burn-in” phenomenon where afterimages persist on the screen may occur if a stationary image is kept displayed on the screen for a long time.)
White dots are seen on projected images. Black dots are seen on projected images.This phenomenon is normal for a DLPTMprojector and is not a malfunction. (A very small number of pixels may visibly or invisibly be persistent all the time, but they are not a sign of system malfunctions. Over 99.99% of the pixels are effective.)
Fine streaks are seen on projected images.This is due to interference with the screen surface and is not a malfunction. Replace the screen or displace the focus a little.Vertical or horizontal streak noise may appear on the projected image, depending on the type of the DVD player, game console or computer you use. In such a case, you can reduce such streak noise by enabling the LPF.
Projected images become wavy.Connect the plugs of the cables to external devices securely.Keep the projector away from equipment generating interfering radio waves.When the keystone adjustment is carried out, the image may not be displayed correctly because of the type of input signal. This isn’t a product malfunction. In this case, readjust the keystone so that the amount of keystone correction is as small as possible.
Hue is not appropriate. Check that the cables connected to the external devices are not broken.
Tint in projected images is incorrect.If the setting of COMPUTER INPUT in the SIGNAL menu is inconsistent with the RGB/YCBroutput setting of the external device even when the input source is other than computer (for example, when the input source is HDMI1 or HDMI2), the entire image appears reddish or greenish.Check that COMPUTER INPUT in the SIGNAL menu is correctly set. (See page 30.)Check that the cable connected to the external device isn’t broken.
Different color tint. When comparing images projected by two projectors, tints in the displayed images may be different because of variation between their optical components. This is not a malfunction.When comparing the image projected by this projector with those displayed on the television or PC monitor, tints in the displayed images may be different because of difference in the range of color reproducibility. This is not a malfunction.
Only the motion areas in the images supplied from the computer aren’t displayed.This is caused by the computer being used. Contact the manufacturer of your computer.
Projected images are obscured.·Match the output resolution of your computer with the resolution of the projector. For the method to change the output resolution of the computer, contact the manufacturer of your computer. (See page 79.)·Some images and texts appear obscured during the keystone adjustment. In such cases, use the projector without applying the keystone adjustment. (See page 17.)
Noise appears around the image.·In some images such as DVD, noise may appear around the recorded image. In this case, decrease the setting value of OVER SCAN of the SIGNAL menu. (See page 30.)
Projected images are flickering.·After the POWER button or ON button on the remote has been pressed, or the LAMP MODE setting has changed, images may be flickering until the lamp lights stably. This is an expected behavior.·When selecting the input signal, AUTO POSITION, and Image, the projected image may be flickering temporarily. This is not a product malfunction.·During LAMP MODE LOW2 is switched, projector images are little bit flickering for a moment with constant timing. This phenpmenon is to keep lamp condition well and is not a malfunction.
Projector images are twitching.·Projector may be vibrating. Set AUTO KEYSTONE to OFF or lower the VOLUME ▼ button of the Remote control.

Others

Problem Solution
The exhaust vents emit warm air.This air comes out after cooling the inside of the projector. You may feel hot, but this vis not a malfunction.

“TEMPERATURE!!” is displayed.This indication appears when the ambient temperature rises high. When the ambient temperature stays high, the lamp goes out.Eliminate any causes of the rise in the ambient temperature.This indication appears when the air inlet or outlet grille is blocked. When they are kept blocked, the lamp goes out.Remove the objects blocking the air inlet or outlet grille.
The mark appears.This mark appears when ineffective operation is carried out. This isn’t a product malfunction.
The remote control doesn’t function easily or at all.Check that the batteries are loaded in the remote control or the batteries are not weak. (See page 9.)Check that the remote control sensor isn’t exposed to direct sunlight or fluorescent light. (See page 9.)Use the remote control within its operation range. (See page 9.)Use the remote control at least 10 cm away from the projector.
The fans sound during standby.When STANDBY MODE is set to STANDARD, the fans rotate at very low speed during standby after plugging the power cord (with 5 second high speed rotation at the beginning) and after turning off the lamp. This is to cool down the projector operating various functions during standby and is not a malfunction.
Abnormal sound is heard.Because the color wheel spins at a high speed, metallic sounds may be heard in rare occasions. Such symptom is not a malfunction.
Fan sound increase suddenly during LAMP MODE "LOW2".During LAMP MODE LOW2 is switched, fan speed increase for a short time once per 30 minutes. This phenomenon is to keep lamp condition well and is not a malfunction.
